Private group or public community? Choose the right Session space

Groups are designed for private collaboration

Session groups use end-to-end encryption and suit families, small teams, and project work. Messages are delivered through the decentralized network rather than a single community server. As membership grows, identity checks, invitation discipline, and clear handling of departing members become more important than the technical label alone.

Communities optimize for reach

A community is a large channel hosted by an operator. Session’s FAQ explains that community messages are encrypted in transit to the server rather than end to end in the same way as private groups. The operator necessarily has a role in hosting history and administering content. That model supports discovery and scale, not the strongest confidentiality.

Route information by sensitivity

Announcements, open discussion, and interest groups fit communities. Identity details, locations, internal documents, or operational plans belong in a verified private group—or should not be sent at all. The fact that both spaces appear in one application does not give them the same privacy properties.
